There are two types of tests one is Nat (its of students taking admission in college/university) and the other on is GAT which is for postgrade admissions. NTS is the first mcqs based assesment organization that started in 2006. The chances of cheating in this test were very low because they give different type of question paper to each individual that sets closer to eachother in the test hall, But previously there were some leaks of this test on social media before paper time and that's why the paper got canceled due to this reason. Nowadays several other alternatives to NTS also exists like Pakistan testing service (pts), Educational testing service(ets) and Allied Testing Service(ats)
